THE GRIMANI FILES: Bringing Life to a Comatose Home Theater

This client was referred to us by the integrator, who completed this installation about 10 years ago. The room was a dedicated three-row home theater in an upscale neighborhood of Detroit. All the gear was state-of-the-art for its time - from the studio-grade speakers, to the professional HD video projection system. But the surround decoder finally gave up the ghost after several years of faithful service. The client heard that Dolby Atmos® was the latest thing, so he sourced a new processor. He expected it to be an automatic upgrade, but wasn’t aware that he also needed to add speakers for the Top and Wide locations.

Progress on Dedicated Private Cinema in Emerald Cove

I'm here in Dana Point, California, doing phase one audio calibration of a dedicated private cinema in the Emerald Cove neighborhood of this upscale community. This phase is all about initial configuration, testing, and debugging of all the audio components in this 7.1 channel system with eight ceiling-mounted subwoofers.  I'm also finishing up with a basic room tuning equalization and will finesse that after the internal finishing of stretch fabric and drape is completed.
